Having done some checking, it is ironic that the whistleblower is a guy who successfully had a discipline charge aginst him overturned by a federal review board. His alleged 'crime' - working late in the office!
From what is published we can't be certain but it is highly likely that a proportion of the ADs relate to Sikorsky products. Certainly the FAA found that EASA beat them to a couple of EADs on the S-92A after the accident when the Europeans made it clear they were not prepared to keep waiting for the FAA.
The fact it goes back 7 years is of interest. That was the time the S-92 was certified.
It was also the time that the Rotorcraft Directorate, for geographic reasons, were in charge of the Eclipse fixed wing certification. FAA had to rush through a special investigation on that in 2008 after congress got interested in the obvious failings. Oronically that happened about the same time as they SHOULD have been focused on Broome.

Very little has been said by CHC about the Broome incident either.
